re r -id o WILLIAM :6. LA ROSE, OF ROCHESTER, NEW

VAPOR BURNER.

Application filed December 22, 1921.

T 0 all whom it may concern Be it known that I, WILLIAM F. LA Been, a citizen of the United States. residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Vapor Burners; and I do hereby declare the fol low ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates .to burners of the type designed to use hydrocarbon as fuel, the same being generated into vapor which is consumed at the burner outlet, the fuel being supplied from a suitable source and the conductor therefor including a chamber disposed in the heating zone of the burner whereby to vaporize the fuel. in its passage through said chamber.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application,

Figure 1 is an elevation of a vapor burner embodying the invention,

Figure 2 is a vertical longitudinal section thereof,

Figure 3 is a top plan view of the burner,

Figure 1 is a horizontal section thereof, the parts being shown on a larger scale, and

Figure 5 is a detail view of a portion of the burner showing more clearly the divisional portion separating the vaporizing and superheating chambers.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The burner comprises a base 1 which is hollow or recessed upon its upper side to constitute a drip pan. A standard 2 rises from the base 1 and is preferably attached thereto. An annular burner tip 3 is supported by the standard 2 and is connected therewith by means of webs 1 which constitute braces.

Serial No. 524-,180.

Radial slots 5 are formed in the upper side of the burner tip 3 and constitute outlets for the fuel. A mixing chamber 6, carried by the standard 2 and preferably forming a part thereof, includes branches 7 which are connected to the annular burner tip The mixing chamber 6 is disposed horizontally and the branches 7 are at the inner end thereof. A snout 8 depends from the outer end of the mixing chamber and constitutes an inlet for air. A valve 9 is coupled to the outer end of the mixing chamber 6 above the snout 8 and a pipe 10 leads therefrom.

An annular chamber 11 is disposed above the annular burner tip 3 and is connected with the latter by means of posts 12 which preferably form a part of the chamber 11 and tip 3. The annular chamber 11 is provided at diametrically opposite points with raised portions 13 which separate the chamber into two parts, the one constituting a vaporizer and the other a superheater. The semicircular portion of the chamber between the pipe 10 and the raised portions 13 constitutes the superheater and the semi-circular portion between the raised portions and a supply pipe 14: constitutes the vaporizer. The superheater is designated at 16 and the vaporizer at 17. The pipe 14 leads from a suitable source of supply and connects with the vaporizer 17 at a central point and the pipe 10 connects with the superheater 16 at a central point.

A centrally disposed pan 18, located below the annular chamber 11 and at the upper end of the standard 2, is adapted to receive a quantity of fluid, such as alcohol, gasoline or the like, which when ignited heats the burner whereby to prime the same 'so that the fuel entering the annular chamber 11 is vaporized preliminary to entering the chamber 6. The fuel entering the part 17 of the annular chamber 11 is vaporized and passes therefrom through the raised portions 13 into the part 16 in which it is superheated before entering the chamber 6. Air is drawn into the chamber 6 through the spout 8 and mixes therein with the vapor prior to entering the burner tip 3 through the passages 7. The gaseous mixture escaping through the outlet of the burner tip is ignited and the resulting flame heats the annular chamber 11 and may be utilized for heating or cooking as required in a manner well. understood.

The valve 9 is of the needle type such as commonly provided in vapor and gas burners.

What is claimed is:

1. In a fuel burner of the character specified, vaporizing and superheating chambers in substantially the same horizontal plane, and upwardly disposed hollow members connecting adjacent ends of the chambers and in communication therewith.

2. In a fuel burner of the character specified, vaporizing and superheating chambers in substantially the same horizontal plane and or? approximately semicircular term, and upwardly extending hollow members connecting adjacent ends of the chambers and in connnunication therewith.

3. A. vapor burner of the character specified comprising an annular chamber having diametrically opposed raised portions dividing the same into a vaporizer and a superheater, means for supplying fuel to the vaporizer at a central point, and a burner supplying pipe having connection with the superheater at a central point.

l. A vapor burner comprising an annular tip, a cent-rally disposed pan, a horizontal mixing chamber, braces connecting the burner tip with the inner end of the mixing a chamber, an air inlet snout depending from the outer end or the mixing chamber, and a valve at the uncture of the snout and mixing chamber.

5. In a vapor burner of the character specified, a standard having braces grouped about its sides, a burner tip supported by said braces, a pan at the top oi the standard and within the burner tip, a horizontally disposed mixing chamber supported by said standard and having its inner end in communication with the burner tip and provided at its outer end with a depending snout, and a valve'at the juncture of the snout and mixing chamber.

6. In a vapor burner of the character specified, a standard having braces grouped about its sides, an annular burner tip sup ported. by said braces, a centrally disposed priming pan at the top of the standard and within the upper ends of the braces, a hori zontally disposed mixing chamber having its inner end in comm-iiinication with the burner tip and provided at its outer end with a depending snout, a valve at the junc= ture of the snout and mixing c'l ianrber, and an annular member above the burner tip having opposed raised hollow portions dividing the annular member into semicircular vaporizing and super-heating chamber-s.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM 1*. LA ROSE.
